How to determine school letter grades using only Duolingo

Does anyone have experience with how one to calculate grades when students are using only duolingo? I read and hear how teachers use duolingo as a supplement, but what if this was used as the core manner of instruction? Does anyone have experience with this?

I'm looking for an alternative to Rosetta Stone and many of the home school families that I work with really like using Duolingo. I'm trying to understand it more and use it as a resource to the families that I work with.

Also, is there a way to export student progress? I'd love to export the data into an excel document.

Thank you!

I would probably advise against using Duolingo, or any app, as the core manner of instruction. Since they're in a classroom, they have so many resources that Duolingo just can't give them, such as conversation practice with real people as well as cultural studies that are often a core piece of language immersion. I would stick with using Duolingo as a supplement, whether it be within the classroom or homework. Many school districts have a set curriculum that you will need to follow, so you may not even be able to use it as a main teaching method.

Another issue is that no matter how good the program is, many students, especially when you get closer to high school, have a very short attention span and will shut down after around 20-30 minutes and you'll have nothing but whining the rest of the class time. This is a really good reason to mix it up. Some students are eager to learn and would be more than happy to spend all day learning through Duolingo, though.

I'd say maybe make it a supplement for practice of about 90 minutes or so spread out over the course of a week. You know your students better than us, though, so you'll need to adjust times based on their feedback.


Although I totally see the value in using Duolingo as a supplement, I am looking for a second option instead of using Rosetta Stone. I work with home school students who are looking for an alternative language provider and so far Duolingo looks pretty good, I am just trying to figure out some of the nuts and bolts. Thank you for your response. :)


Home school could very well be a different story. My experience lies mainly with a gamified math program used with a large group of ESL students. We had one small group of about 4 students using it that were very willing to do it for an entire class period. Most classes were around 15-20 students and their attention span went fast. Since home schooling is more one-on-one, you may have much better luck.

Although, as I said, it does lack a lot of the resources that are normally found in classroom settings, so if you do try to use it as a focus, supplement as much as possible so that they get a more well-rounded language education.


I think you might need to devise a test that wasn't actually on Duolingo, but that written by someone who had done the course. The course is really only set up to be self learning for adults or a supplement for a full course, so there isn't really a good way of checking learning other than the progress quizzes. Those might be something, but then, they won't show whether you know specific things, but how well you have done compared to the best you can do in the context of the whole course, so it wouldn't be the same as giving a test on the first third of the tree.


Duolingo can absolutely be used in Home School settings. Of course having a teacher designed, well-rounded and carefully planned full curriculum is best so that students get everything they need. However, we must remember that some schools, communities, and parents do not have access to a traditional language class. There are even schools that do not offer language classes. Duolingo is a great motivator and guide in those situations. We of course recommend that the person leading the learning experience makes sure there is enough dialogue, listening and writing practice to enhance the experience students are getting with Duolingo.

The letter grades depend a lot on the level you grade on. For example, you can provide grades based on how many students delivered their assignments on time (effort). Or create pre- and post tests they can take to measure their improvement, and grade them on the final results. You can also divide into create spelling tests that or listening tests (and the like) that can all count towards a grade. Let us know what you end up doing! How were you grading before?
